I am using Yahoo Messenger . What about you ? If you want to chat , add me on messenger ( id is on profile, only webmasters chat! )
i use msn. i used to use yahoo, but their is a lot of "booters" which logs u out and i am in love with MSN lol. a few people told me to use XFire but i have never tried it. - for anyone who wants it. NO SPAM AND ENGLISH ONLY!
Google Talk Rulez .. I think G Talk is best way, becouse you dont need to concentrate other programs while you re working..
There is no doubt that yahoo messenger dominates in this world but still google talk is far much better. You will definetly say that I am wrong because it lacks few features but still its worthy...
I think yahoo had the best IM + chat combo until it started getting spammed ( don't know why people do it with links like ertertretretertre.com/dfgdffgdftreterterrtert no one is clicking these). But the messenger still is my fav.
